Don’t cancel flight topic

I was to return home on Dec. 30 from Vancouver to fly back to Castlegar. I had checked in, gone through security, and finally got to the gate, only to be informed flights to Castlegar had been cancelled. I checked online the following morning, and flights given ‘green light.’ Back to the airport and while checking in, we were informed that the flight schedule was reversed shortly after we all left. Chatting with others going to Castlegar ‘again’, Air Canada didn’t phone anyone to inform them flights schedule reversed.
